DRYlNG-MACHINE.

v5.1.3111GIFIGATION forming part of Letters latent No. 543,578, datedJuly 30, 1895.

Application-tiled November 25| 1892. Serial No. 453,014. (No model.)

a drying-machine in Which the material will be subjected to the actionof the drying medlum in a more thorough manner than heretofore.

-The invention consists in the peculiar construction of thedrying-,cylinders and the means for introducing dry air or otheroxidizing medium to the interior of the same.

The invention further consists in the combination of a number ofpeculiarly-constructed drying-cylinders with suitable standards inclosedwithin a chamber and having airsupply pipes, as will hereinafter be morefully described, and pointed out in the claim.

Figure 1 represents an elevation of one form of the improveddrying-machine, the wall of the inclosing-chamber being shown insection. Fig. 2 represents an enlarged crosssectional View of one of thedrying-cylinders.

Fig. 3 representsalongitudinal sectional view of the same to moreclearly indicate its construction and the connection with the airsupply.

Similar numbers of reference designate corresponding parts throughout.

In the drawings, 5 5 indicate cylinders or cages formed of the ends 6 6having circumferential gears 7 and tho bearing-collars 8. The ends 6 6are connectedby the bars or rods 9 9, the bearing-collars 8 beingjournaled on the., sleeves 10, which are rigidly secured in the hubs 11of the brackets 12. On the internal ends of the sleeves 10 are shoulders13, which bear against the inner surfaces of the ends 6 6, and inwardlybeyond these shoulders are the spiders 14, which may have any number ofbranch connections 15, the corresponding branches at the opposite endsof the cylinder being connected by the pipes'or tubes 16, the ends ofwhich are curved to t into the branches of the spiders, While the mainlength ot' the tubes extends parallel to and slightly within the bars orrods 9 9, the outer surface of these tubes or pipes 16 being furnishedwith the longitudinal slots 17.

Dry and heated air or other oxidizing medium is admitted to the sleeves10 and thence to the tubes 16 by means of the supply-mains 18, havingbranches 19, which connect with the outer ends of the sleeves 10, themains 1S being connected with an air-blast ot' any usual and ordinaryform.

When arranged in Vertical series, as shown in Fig; 1 of the drawings,the brackets 12 eX- tend alternately from opposite sides of thestandards 2O and are located with reference to the diameter of thecylinder-heads 6, so that the gear-teeth 7 of each pair of headsintermesli with the gear-teeth of the heads next above and below, so that,by driving one `cylinder in each series, rotation will be imparted tothe remaining cylinders. In this construction the gears 2l are journaledin bearings mounted on the cross-bars 22 and intermesh with the gears ona cylinder of each of the vertical series, these gears 21 being drivenby the gears 23 mounted on the drive-shaft 24, the ends ot" which aresuitably journaled, this drive-shaft being driven in any usual manner.

The series of cylinders are contained Within the chamber 25, and thecloth or other material to be operated on passes into the same through asuitable opening. It then passes partially around each ofthe cylindersin turn, being subjected to the action of heated air which is forcedthrough the slots in the tubes 16, and by this means is thoroughly driedwithout being brought into contact with the heated metal of the tubes.

It is obvious that any number of the cylindrical cages may be used ineach series. The cylinders may be of any diameter and length, and theymay` be journaled in horizontal frames, if desired, modifications beingmade in the size and shape of the inclosing-chamber, or this chamber maybe dispensed with when it is not necessary to coniine the heated airescaping from the cylinders.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In a drying or oxidizing machine, the combinationwith an inclosing chamber having an inlet and an outlet through whichthe fabric to be treated may be passed,of the standards -20-20 mountedwithin the chamber and furnished with the brackets 12--12 extendingalternately in opposite directions, the crossbars 22 connecting thestandardsinpairs, the sleeves 1.0--10 mounted in the brackets 12-12 andfurnished with the spiders 14 having branched outlets 15, theslotted-tubes 16 connecting the corresponding branches of the spiders,cylindrical cages formed by the heads 6-6 connected by the rods 9-9 andhaving In witness whereof I have hereunto set my hand.
